64° on Nov. 17, 2020, the hottest reading for this week of the year since 1980. Next is 62° in 1990.
Port Hadlock-Irondale’s center stands about 170 ft above sea level. Within three miles the land runs from 10 ft to 660 ft, a difference of 650 ft: hilly country. Open water lies within three miles. The highest named summit within 15 miles is Green Mountain, about 4,380 ft, 15 miles southwest.
Under the town center the state geologic map shows Middle and lower Eocene volcanic rocks (basalt), from the Early Paleocene to Middle Eocene, 40 to 64 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 7×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, siltstone. Age: Middle Eocene to Early Miocene, 16 to 48 million years old. About 5 mi of the line.
Sandstone. Age: Early Eocene to Middle Eocene, 38 to 56 million years old. About 5 mi of the line.
Basalt. Age: Early Paleocene to Middle Eocene, 40 to 64 million years old. About 4 mi of the line.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
